How to Make Sky High Chocolate Mousse Pie
Ingredients
- 22 regular Oreo cookies (not Double Stuf)
- 5 Tablespoons (71g) unsalted butter, melted
- 8 ounces (226g) unsweetened chocolate, finely chopped (two 4-ounce bars)
- 2 Tablespoons (28g) unsalted butter
- 4 large egg whites* (120g)
- 1 cup (200g) granulated sugar
- 1/4 teaspoon cream of tartar*
- 2 cups (480g/ml) heavy cream, cold
- 6 whole Oreos, crushed into crumbs (68g)
- 1 cup (240g/ml) heavy cream, cold
- 2 Tablespoons granulated sugar
- 1/2 teaspoon pure vanilla extract
- Optional: chocolate curls or shavings for topping*
Directions
- Preheat the oven to 350°F (177°C). In a food processor, pulse 22 Oreos into fine crumbs. Pour into a medium bowl and mix with the melted butter. Press this mixture into the bottom and sides of a 9-inch pie dish. Bake for 10 minutes, then let cool completely.
- Microwave the chopped chocolate and 2 tablespoons of butter together in a heat-proof bowl, stirring every 20 seconds until melted. Set aside.
- In another heat-proof bowl, combine egg whites, sugar, and cream of tartar. Place the bowl over a saucepan of simmering water (but don’t let it touch the water). Whisk constantly until the mixture reaches 160°F (71°C).
- Transfer the mixture to a mixer and beat on high speed until soft peaks form, about 5–6 minutes. Gently fold the melted chocolate into the egg whites.
- In a separate bowl, whip 2 cups of heavy cream until medium-to-stiff peaks form. Fold this into the chocolate mixture carefully.
- Spoon half of the mousse into the cooled crust. Sprinkle the crushed cookie crumbs on top, then layer the remaining mousse, forming a dome shape in the center. Refrigerate the pie.
- For the topping, whip 1 cup of heavy cream with sugar and vanilla until medium peaks form. Spread this whipped cream on top of the mousse, keeping the dome shape. Add chocolate shavings if desired.
- Refrigerate uncovered for at least 4 hours or up to 1 day. Allow the pie to sit at room temperature for 10 minutes before slicing and serving. Store leftovers covered in the fridge for up to 4 days.
